2 Claims. (Cl. 30-30) This invention relates to tonsorial equipment andmore particularly to hair cutting devices whether for use as razors orhair planers.

The principal object of the invention is to provide a novel and improvedimplement of the class described which is efficient in operation, com`-paratively simple in construction, requiring a minimum number of parts,and easy to assemble, manipulate, and dismantle for cleaning orsharpening.

The invention in its preferred embodiment contemplates the provision ofa folding combination implement comprising a hair planer and a razor,each of such instrumentalities having a handle extending therefrom andpivotally or hingedly connected at their respective ends, whereby theinstrumentalities may be folded together, one upon the other, when notin use.

One feature of novelty of the invention resides in the provision ofnovel locking means for securing the blades and guards to the bodyportions of the respective implements.

Another important feature of the invention is the provision, in the hairtrimmer or planer, of a blade having a notched or serrated edge, and theclamping of such blade edge by novel means which not only attains abetter angular shearing cut but serves to reinforce or back up theserrations or teeth during the cutting operation.

Other objects and features of novelty will be apparent from thefollowing specification when read in connection with the accompanyingdrawings in which one embodiment of the invention is illustrated by wayof example.

In the drawings:

Figure 1 is a plan view of a combination implement embodying theprinciples of the invention,

Figure 2 is a greatly enlarged fragmentary plan view of the hair planerportion of the device, showing the novel arrangement of blade teeth orserrations and the guard tines or projections,

Figure 3 is a transverse sectional view taken on line 3--3 of Figure 1,with the complementary portion of the implement indicated in brokenlines in the position it occupies when the device is folded together,

Figure 4 is a transverse sectional view taken on line 4 4 of Figure 1,

Figure 5 is an exploded perspective view of a hair trimmer blade and oneof the removable guard members; and

Figure 6 is a fragmentary transverse sectional view taken on line 6-6 ofFigure 1.

The device as a whole is designated by the reference numeral I0 and willbe seen to comprise two very similar instrumentalities hinged togetherfor alternative use and for convenient disposal when not in use. Thehair trimmer or planer portion'of the device is designated by thenumeral II while the razor portion is denominated I2. Each of the twoinstrumentalities may be provided with suitable handle portions I3, theends of which are pivotally connected as at I5. Any suitable riveted orbolted hinge joint may be provided at this point, a. most suitable onebeing a spring joint by means of which the two implements would be urgedtogether when in closed position as Suggested in Figure 3.

The body portion of each of the instrumentalities II and l2 are verysimilar in construction, each comprising a substantially rectangularplate of arched cross section, these plate-like body members beingdesignated I'I in the case of the razor part I2 and I6 in the case ofthe hair planer II. The arched or concavo-convex cross-sectionalconflguration of the members is clearly shown in Figures 3 and 4.

Along both longitudinal' margins of the body portions I6 andII'there'are provided a number of tines, projections, or teeth I8separated by the gaps or spaces I9.

Now referring more particularly to the lower right hand portion ofFigure 1 and to Figure 4 of the drawings, it will be seen that the razorportion I2 of the device is further provided with a. somewhat curved orarched guard or clamping member 20 which has a straight rectilinear edgealong both lateral margins as indicated at 2|. The guard plate or clamp20 serves to iirmly grip the razor blade 22 between its concave innerface and the convex face of the body member I1, the cutting edges 24 ofthe razor blade extending across the gaps I9 between the teeth I8 of thebody plate I1 in the conventional way.

The clamping guard member 20 is provided centrally thereof upon itsconcave side with a post 25 which may be secured in any suitable manneras by a forced fit within an opening in the member20, by Welding, or bymeans of the threaded stud connection 26. The periphery of the post 25near its outer end is provided with a groove 21 which rotatably receivesthe margins of acentral opening in the swivelled locking bar 28.Conveniently, this connection may be made by forming an attenuated endupon post 25 which will readily t within theopening in the bar 28 andthen heading or peening over the end of the post 25.

Both the razor blade 22 and the frame member I1 are provided centrallywith a longitudinally of 90 tothe transverse position indicated in theFigures 1 and 4; The pressure of the curved ends 29 of the bar 28against the concave undersurface of the frame member I1 ofthe razor I2will serve to draw the guard member into iirm clamping relationship withthe blade, and bend the normally fiat blade into a curved configurationconforming to the surface of a cylinder of great radius.

Forv the purpose of, properly positioning the blade and clamp upon theframe I1, guide pins or studs 30 are provided on the convex side oftheframe plate I1. These-pins pass through openings in the razor blade 22and may be received in openings or recesses in the inner face of theguard member 20.

.The fastening 'means for the hair trimmer or planer blade 36 is verysimilar to the means which f has just been described in connection withthe razor I2 and the same reference numerals will be 'applied to many ofthese parts. .The clamping guard corresponding to the guard 20 of therazor, is designated and is provided with the post'25 having theswivelled locking barv 28 thereon, which passes through the opening 4I)in theblade 36 andthence through the similar opening 42 in the frame I6,whereupon it is swung to a transverse position and clamping pressureapplied to the blade.` The positioning studs 30 carried by the framemember I6 pass throughthe small, preferably oiset, openings in the blade36 and thence through openings 48 in the guard member 20. Thispositioning or centering feature will be clearly understood byinspection of Figures 1, 5, and 6.

When the two instruments are swung around the pivot I5 to parallelpositions they appear as the individual cutting teeth of the blade andkeep them firmly in position with'relation to the tines I8, thusinsuring close contact at the angles or notches 55, and preventingpinching or pulling of the hair.

' Various changes and modifications may be made in the embodimentsillustrated and described herein without` departing from the scope ofthe invention as defined by the following claims.

Having thus described the invention, what is claimed as new and desiredto be secured by Letters Patent is:

1. A tonsorial implement of the class described comprising, incombination, a pair of clamping guard plate's, each of said plates beingrelatively iiat, substantially rectangular, segmental section ofcylinders of large radius, the plates being slightly concavo-convex intransverse section, at least one of said plates having guard teeth alongat least one edge thereof, a cutting .blade interposed between saidplates and having a cutting edge disposed adjacent the teeth on saidplate, a stud on one of said plates having a locking bar mounted on theend thereof for swivelling movement in a plane substantiallyparallelwith the general approximate planes of said plates, elongatedregistering openings'in said blade and the other of said plates throughwhich said stud and 'said lbar may be passed when the stud is in oneposition, said bar adapted to be swung through suggested in Figure 3,and the folded device may be conveniently laid away or disposed in asuitable receptacle until ready for use.

One of the most important features of the invention relates to theconfiguration and arrangement of the hair trimmer bladeA 36, and thiswill now be' described with particular reference to Figures 1 and 2 ofthe drawings. The blade 36 has its two edges provided with serrationsorteeth such as shown at 50, these serrations preferably being roundedat theirouter edges as at 5I and .merging to form V-shaped notches 52between each of the teeth or serrations. The blade teeth 50 arestaggered with relation tothe teeth or tines Iii of the base plate I6,the arcuate cutting edges 5I of the teeth extending across the gaps I9between the tines I8 this arcuate cutting edge making an arcuate angle,as at 55, with the edges of the guard teeth I8, this provision affordinga shearing arrangement whereby the strands of hair which are not cut bythe intermediate portion 5I of the teeth will be cut when they arewedged into the angles or notches 55.

` Unlike the razor guard member 20, the guard or clamp 35 for the hairtrimmer I I is provided along both its longitudinal edges with theserrations or teeth 51, which coincide with the teeth 50 of the cuttingblade 36, but are set back slightly from the edges of the teeth asclearly indicated in Figure 2. Thus the guard teeth 51 serve toreinforce an angle of substantially exerting increasing clampingpressure upon the blade as the ends of` the bar move along the curvedouter concave sur. face of said other plate to a iinal chordwiseposition.

2. A-t0nsoria1 implement of the class described comprising, incombination, a pair of clampingguard plates, one of said plates havingguard teeth along at least one edge thereof, a cutting blade interposedbetween said plates and having a cutting edge disposed adjacent theteeth on said plate, and means for causing said plates to exertclampingpressure upon said blade, the cutting edge of the blade beingprovided with arcuate teeth, said teeth alternating with the teeth ofthe first guard plate, and the side edges of said respective adjacentteeth of the blade and guard platel converging to provide asubstantially V- shaped notch, .wherein hair may be cut by a.

shearing action, said guard plate teeth projectingv outwardly beyond theteeth of said blade, the other of said plates also being provided withteeth along its edge adjacent the cutting edge of the blade, the lastnamed teeth being staggered with respect to the teeth of the iirst namedplate but registering with the teeth of said blade and bearingrespectively against the blade teeth to apply clamping pressure close tothe cutting edges thereof.
